Bug#267853: ant: bug when symlinking jre/lib/ext with Sun's j2sdk1.4

[Morten Werner Olsen]

Package: ant
Severity: minor

I have a problem with ant when installing Sun's j2sdk1.4 (for
installation procedure, se item 1 in [1]). The problem seems to be
related to that I symlink /usr/lib/j2sdk1.4-sun/jre/lib/ext to
/usr/share/java. If I don't use this symlink, ant works ok:

  austin:/usr/lib/j2sdk1.4-sun/jre/lib# ant
  Buildfile: build.xml does not exist!
  Build failed
  austin:/usr/lib/j2sdk1.4-sun/jre/lib# cp ext/* /usr/share/java/
  austin:/usr/lib/j2sdk1.4-sun/jre/lib# mv ext/ ext-old
  austin:/usr/lib/j2sdk1.4-sun/jre/lib# ln -s /usr/share/java ext
  austin:/usr/lib/j2sdk1.4-sun/jre/lib# ant

  austin:/usr/lib/j2sdk1.4-sun/jre/lib# ant
  Buildfile: build.xml does not exist!
  Build failed
  austin:/usr/lib/j2sdk1.4-sun/jre/lib#

I assume that the bug is in ant, because other java-applications I use
works just fine.
